History

Symptom: "rados/singleton-nomsgr/{all/lfn-upgrade-hammer.yaml rados.yaml}" fails because, after last upgraded node is rebooted, cluster gets stuck in "HEALTH_WARN all OSDs are running jewel or later but the 'require_jewel_osds' osdmap flag is not set"

Root cause: the test does not issue the "ceph osd set require_jewel_osds" command after rebooting the last upgraded node.
